efficiency of ruminants to utilize such a wide variety of feeds is due to highly diversified rumen microbial ecosystem consisting of bacteria (1010–1011 cells/ml‚ representing more than 50 genera)‚ ciliate protozoa (104–106/ml‚ from 25 genera)‚ anaerobic fungi (103–105 zoospores/ml‚ representing five genera) and bacteriophages (108–109/ml)1. These numbers might even be larger as majority of them are non-culturable. The synergism and antagonism among the different groups of microbes and even among different

the commercial chitosan. FT-IR spectra gave characteristics bands of –NH2 at 3431cm-1 and carbonyl at 1661cm-1. X-ray diffraction (XRD) patterns also indicated two characteristics crystalline peaks approximately at 10° and 20° (2θ).The surface morphology was examined using scanning electron microscopy (SEM). 4|Page Preparation of Chitosan from Jazan Area Shrimp wastes and Investigation of Its Properties KEY WORDS 5|Page Preparation of Chitosan from Jazan Area Shrimp wastes and Investigation

Size and morphological analysis The morphology and size of nano-ZrO2 was studied by Field emission scanning electron microscope (FESEM)‚ model JEOL JSM7600F. Scanning electron microscopic (SEM) analysis was done to determine the morphology and pore dimensions of prepared nanocomposites (BNC I-III). SEM was performed using EVO-18‚ Carl-Zeiss instrument. For both of these analyses‚ samples

Paul Jackson November 30‚ 2011 ANT 1010 Michelle Lappegarrd Language of the Neanderthal It is understood that the Neanderthal was an exceptional thinker and communicator; but there are heavy debates that question whether or not it spoke with a language. Some argue that the hyoid bone of the Neanderthal was too high in relation to its larynx to enable its tongue to form words‚ while others argue the opposite. With respect to both theories‚ it was indeed a linguistic hominid. The Neanderthal

then reverting from 3’C to -25’C between the months of July to December. Through those temperatures it causes a cycle of thawing and freezing of the soil. During the short time of the temperature rising‚ the ground thaws out making the soil soggy and wet; but refreezes again in the winter‚ causing the the roots of small plants to tear apart‚ negatively affecting their growth. Abiotic factors such as the cold weather‚ the worn down soil‚ the blistering winds‚ and shorts growing seasons are also reasons
